[introduction] all previous development via 70 one’s remaining years, radar technology reached the respect such as technical application to already obtained very great progress in method of academic, system, implementation. But in recent years, traditional radar explores function to already approached classical physics limit, how to promote radar system performance to become the difficult problem that puzzles brainpower further.   All previous development via 70 one’s remaining years, radar technology reached the respect such as technical application to already obtained…

[introduction] the progress that produces as industry, it is very as important as control that temperature is measured, of temperature parameter accurate measure efficiency of qualitative to export, production and on the safe side move crucial. ADI is had measure perfectly lukewarm / dominate lukewarm program, from Thermocouple (TC) of RTD of passive detector of resistor type temperature, thermocouple, to direct electric current / the semiconductor temperature sensor of output of output of voltage imitate capacity, SPI/IIC number interface.  …

[introduction] noise can be random signal or heavy reply date, interior or exterior generation, voltage or voltaic form belt or broadband, high frequency or low frequency. (here, we define noise the useless signal that puts output end to allow why to carrying)   Noise can be random signal or heavy reply date, interior or exterior generation, voltage or voltaic form belt or broadband, high frequency or low frequency. (here, we define noise the useless signal that puts output end to…

[introduction] the development trend of industrial electron product is smaller circuit board dimension, more fashionable appearance and provide cost effectiveness more. As a result of these trends, personnel of electronic system design must reduce printed circuit board (PCB) dimension and cost. Use spot but array of process designing door (FPGA) and piece on system (SoC) industrial system needs course of many power source, face the challenge of small size and low cost at the same time.   The development trend…

[introduction] did you ever serve as sound control fader with too linear potentiometer? If you had been used, you may discover, volume jumps become very fast. If want to adjust volume quite smally, you may need the acute touch like Safe-cracker. Need logarithm potentiometer at this moment.   Did you ever serve as sound control fader with too linear potentiometer? If you had been used, you may discover, volume jumps become very fast. If want to adjust volume quite smally,…

[introduction] voltage control current source (VCCs) is used extensively at the numerous domain such as automation of medical apparatus and instruments, industry. Function of the dc precision of VCCs, communication and force of drive kinetic energy are in these application crucial. The article was analysed increase model Howland current source (the limitation of EHCS) circuit, elaborated how to use compound amplifier develop attacks undertake improvement, in order to realize the high accuracy, ±500 MA current source that establishs quickly.  …
